I am a female and i did one line of cocaine around 4pm and i could have a drug test in the morning do u think i will pass a urine test?

Unlikely: Your urine will have metabolite of cocaine. Unless the cut-off is set too high your will test positive. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex.
